- The history of bridges
Early bridges were made of stone, wood and concrete. The arrival of the steam train in the mid-18th century ushered in a new era in bridge design. A stronger material was needed as bridges were required to carry heavier loads over longer spans.
- Types of bridges
Bridges of today show the advancements in steel technology and design which have occurred over the last century. From the modest spans to the exciting cable stayed and suspension bridges, steel has a wide appeal.
- Bridge case studies
In 2005, worldsteel completed a project on bridges. Its aim was to share information and promote the use of steel in bridge construction.
